3.2.2 Effect of plateau pika disturbance intensity on plant species richness
Accounting for the five-site scale effect, the plant species richness increased and then decreased as the plateau pika disturbance intensity increased (Figure. 7A). Accounting for one site effect, the plant species richness showed hump-shaped trends at Gangcha, Haiyan and Qilian and increased linearly at Luqu and Gonghe with increasing disturbance intensity (Figure. 7B).
